I don't speak for your society, but this isn't true of mine.
To be clear, where is your society at and are you guys taking people from mine? Lol, because people getting the utter shit beat out of them by the police irrationally and with zero consequences is remarkably common here in America.
I have managed to avoid it, but I know more than a few people who’ve been roughed up in bad faith…
What country are you in? I'd be shocked if any country allowed it's citizens the legal right to use violence against the government.
